Does revving the engine charge the battery faster?
Yes, it was true then, and it’s true now.
The battery will charge faster if you rev the engine faster.
And the faster the alternator turns, the more electricity it produces to run all the electrical stuff in the car — and recharge the battery.
At what speed do cars get best mileage?
The Energy Saving Trust says that the most efficient speed you can travel in a car in terms of achieving the best fuel economy is 55-65mph. Any faster, though, and the fuel efficiency decreases rapidly. For example, driving at 85mph uses 40% more fuel than at 70mph (oh, and it’s illegal too).
Do you save gas by going slower?
Going slower technically saves fuel because at high speed your engine needs to work harder to overcome drag from wind resistance, your tyres and transmission, and that drag increases exponentially the faster you go. Reduce your speed, then less power (and thus fuel) needs to be expended to overcome that drag.
Does redlining damage the engine?
Redlining will not damage an engine or cause it to explode, no matter how cruelly you treat it. Therefore, revving the engine to its maximum speed several times a week is not a problem. Just remember never to do this while the engine is still cold!
Is revving your car illegal?
Revving your engine isn’t illegal. Neither is taking off quickly from a stop light as long as you don’t exceed the posted speed limit or spin your tires. If you spin your tires you could be charged with “Speed Contest”, and/or, “Reckless Driving”.
Is driving 80 mph bad for your car?
Driving at 80 mph will decrease fuel economy and therefore increase fuel consumption; fuel costs will be higher and CO2 (and other harmful gas) output will be higher. Our limited supply of fuel will be depleted faster if we all drive at 80 mph than if we drive at 70 mph.
Is it OK to rev a car in park?
Answer is….its ok to rev you engine in neutral/park. Just not when its cold and dont hold it on rev limiter! Try not to, because free revving can damage the engine.
What RPM is most fuel efficient?
In general, the economical band for petrol vehicles is between 1,500 and 2,500 rpm (for diesels it is between 1,300 rpm and 2,000 rpm), and these bands are the same for the vast majority of vehicles, Sale says. “The exception to the rules are vehicles which have either a very high or a very low power to weight ratio.
Does high rpm hurt engine?
High RPM get much worse nearing max RPM. Max RPM is the limit that the engine can take before severe damage. Running at or near max RPM for extended periods will drastically reduce engine life. Engines are usually more efficient at lower RPM as well.
Is Hard acceleration bad for your car?
Some drivers have been taught not to dart off from a stop, and that’s usually smart. But accelerating extra slow prevents your engine from normal driving conditions and can make the transmission and engine work extra hard. Drive at about the same speed as the autos around you.
Can you ruin your engine by revving it?
Revving the engine won’t speed up the process. In fact, that could cause easily avoided damage. Cold revving causes abrupt temperature changes that create stress between the engine’s tight-fitting components.
Is it better to accelerate fast or slow?
Accelerating quickly requires more energy than accelerating slowly. There is a super-linear releationship between rate of acceleration and rate of fuel consumption (more fuel consumed per meter/second^2 at higher rates of of acceleration).
Why is revving your engine bad?
When you rev your engine, you place additional and unnecessary stress on your car and its engine. This is imperative when it’s cold outside—revving your engine before it has had time to warm up is especially damaging, as the engine’s oil hasn’t had sufficient time to circulate and properly lubricate your car.

How often should u start a car?
To avoid a dead battery, you can start your car once a week and let it run for about 5-10 minutes. (If your car is parked in a garage, be sure to do this with the garage door open to ensure proper ventilation for exhaust fumes.)
What happens if you rev your car too much?
If an engine goes overspeed, commonly called “over-revving”, damage to the piston and valvetrain may occur when a valve stays open longer than usual. Valve float can possibly result in loss of compression, misfire, or a valve and piston colliding with each other.
Is it bad to start your car and drive right away?
Warming up your car in winter before driving it is actually terrible for your engine. According to Popular Mechanics, driving your car right away is the fastest way to warm up your engine, and will actually prolong the life of your engine instead of letting it sit idly before driving.
Is it bad to rev engine in neutral?
Yes, this causes engine wear. When the transmission is in neutral and the engine is “revved” without any load, the spinning engine internals will accelerate, gathering rotational and lateral forces at a faster rate than designed by the manufacturer. Rapidly revving an engine will heat up the piston rings much faster.
